The slide screw member F comprises" the head 19 nd the axial extension 27 of the upper end knuckle body cr head 19 and the said extension comprises a cylindrical portion 28 adjacent the head 19 and below said cylindrical portion a threaded portion l29 provided with an especially steep thread 30, and is axially pierced by a bore of different diameters comprising at the upper portion a relatively 'enlarged portion constituting the hole 24, a second enlarged and threaded portion 31 at the lower end, and which is somewhat elongated, and intermediate the said ends and at the middle body portion a relatively reduced portion 32 that is a fit for the upper pin I, and adjacent the upper 'end comprises the chamber already described.

The spring adjust-ing sleeve J comprisesl an elongated cylindrical member, screw threaded on the exterior, provided with an axial hole 33 of polygonal cross section, shown as square, the exterior being a fit for the threaded lower portion 31 of the bore of the slide screw member F, and which axial hole 33 is a tit for the square lower end 34 of the upper axial pin I. The lower end 44 of the spring adjusting sleeve J may be closed, as shown.

The axial pin I receives the knob H at the upper end and extends downward from the said upper end and in succession passes through the holding nut D, packing washer M, t-he intermediate reduced portion 32 of the bore in the slide screw member F and has the lower end engaged with the axial hole in the adjust-ing sleeve J.

The bottom ller kmember G comprises the lower bodyportion 19 having the upper surface 25 provided with a raceway as men tionedfor a ball bearing andan axial extension 35 extending upward therefrom having a cylindrical lateral wall and plane up- .per end wall, and is provided with an axial bore comprising at the lower end the relatively enlarged and vscrew threaded portion constituting ,the hole 24, and the lower chamber 37 adjacent'thereto and a reduced portion 36' at the upper end that is a lit fork the body portion ofhthe lower pin K. The lower pin K receives the lower knob H at its lower end, and to which it is secured by the radial pinv 39, and extends upward therefrom and passes in succession through the axial bore 26 of the holding nut A1),'. the

chamber 37 and the bore 36 in the filler member G, and the upper endeas it extends upwardly from the extension 35 passes in succession through a packing group L coinprising a bottom end washer 41 of sheet metal, anintermediate packing washer 42 'of suitable flexible packing material, and a top backing' washer 43, and the extreme upper end 39 is square-in cross-section, suitably to engage with the axial hole 40 in the check regulating piece N, which also has a sognare cross section, and the pin K is itself sup-v ported against falling downward and out the engagement of the body portions 18 of the holding nuts D with the holes 1T in the said end knuckle portions 16. The head 21 of the holding nut D coperates to hold the end knuckle portion 16 in the channel 23 and overhangs thesaid ehd knuckle portion 16 laterally and engages with the bearing surface 22 on the outer end of the end knuckle` body portion 19.

The rightleaf member C comprises the leaf proper 15 and overhangingthe lateral edge of the same on one side is an intermediate knuckle portion 45 in the form of a flat plate that is rolled `over to form a cylindrical shell-like structure having a generally cylindrical interior chamber Q and axially positioned between the end knuckles E.

The intermediate knuckle proper R is a composite structure, comprising for the greater portion of thelength the interme' ..diate knuckle portion 45 and 'at the ends. thereof the heads 46 of the cup members P.

lio

the cylindrical body portion/47 suitable on the innerface to engage with the end of the intermediate knuckle portion 45. members P comprise the cylindrical body portion 47 .and head 46 referred to, the said cylindrical body portion 4'? being threaded `on the exterior and a tit for the correspondingly threaded outer endof the intermediate knuckle portion 45, and is pierced by an axial cylindrical bore 49..4 The lower cup member P is ofv suchlength that the upper end thereof is substantially flushwith the upper en'd of the axial extension 35 ofthe filler member G andV 1sl provided vwith' screw holes 48 for receiving the screws-85 that hold the packi o' `group L, and the axial bore 49 is ja titnfedr the said extension TheA cup 35. The bore 49 o the upper c up member P is a lit for the cylindrical port-ion 28 of the extension 2T of the slide screw member F.

The lateral wall of the chamber Q is generally cylindrical and has operatively housed'therein a traveling member or carl '-riage S, spring T, contact diskU, and a side wall and at the upper end with a pairA quantity of liquid V suitable for checking the closing of the hinge A. under normal conditions of operation, is provided at the oflaterally disposed and longitudinally exerally ofthe chamber Q.

tending keys 50 and adjacent the lower end with a laterally and outwardly recessed or enlarged portion 51. The said recessed porf, tion 51. is separated from the threaded lower end of the lateral wall of the chamber Q lby the cylindrical section 52 'of the same diameter as that of the interior wall genthread that fits the thread 30 of the sliding screw. member F, the outer periphery of which is a titfor the wall of the chamber Q and has on,t.he outer periphery a pair of keywa-ys 5G suitable for engaging with the keys 50 and operative to permit axial movement of the carriage S and to prevent rotative movement thereof. 1

The contact disk U bridges the interior of the chamber Q and is positioned between the lower end of the spring adjusting sleeve J 'and the upper endof the spring T. The

lower end of the spring T bears on an annular seat on the upper side of the disk-like plunger proper 57 forming the lower end of the plunger member 54. Theplunger member 54 comprises the said disk-like plunger proper 57 at the lower end, and which fits the general interior wall of the chamber Q and an elongated sleeve like axial extension 58 extending axially upwardly therefrom, and is piercedby an axial bore that comprises a main Vbore 59 of appre" ciable diameter and internally threaded extending the greater part of the length of the said extension from the bottom end upwardand is reduced at the upper endto a small, somewhat restricted outlet 60, and

the connecting wall 61 between the same and the main bore 59 is conical suitably to fo'rm a middle valve seat.

In the normal position, when the carriage4 S is at its lowermost position the plunger member-54 rests on the lbacking washer 43V' andthe upper surface vof the plunger proper 54 is approximately at the lower end of the the upper part of the lower cylindrical sec- .tion 52 of the chamber Qthat is not. lled by the packing group L and which part constitutes the cylinder proper. The check regulating piece N comprises an elongated member threaded on the exterior to fit the threaded portion 59 of the plunger member 54 and somewhat shorter than the same,

closed atthe upper end, has the outer wall 62 at the said upper end suitably shaped to operate as a needle valve in cooperation with the seattil and is provided below the said upper wall with an axial hole -63 shown in Fig. 5a that is square in cross i section suitably to fit the square upper end 39 of the lower pin K and to be slidable axially thereon and the outer periphery ,1s

provided with a plurality of longitudinal y iutes 64. The longitudinal tintes 64 permit free passage of the checking liquid along the length of the check regulating piece N and in operation serve to permit such free passage from below the plunger54 to the upper end thereof,-and to the restricted space or passage provided betweenthe needle valve 62 and the needle valve seat 61.

As described, turning the lower pin K cperates to raise 'or lower the check regulating piece N and thereby check the HowV of liquid V through the needle valve described, particularly so when the leaf members B and C are brought to normal position by A t-he pring T pushing the carriage S downwar I n use, the leaf members B and Carenormally held inthe extended position by the spring T and when moved from such normal position the slide nut 53 is turned relatively to the slide screw member F, resulting in raising the slide nut 53 and the carriage S-including the plunger proper 54, and carrying with it without effective resistance the body of vthe liquid V and in opposition to the spring T, and the thickness of the plunger proper 54 is such that a movement corresponding to lthe normal amount of opening a door will bring the bottom end thereof above the bot-tom 4edge of the recessed portion 51 and will permit Vliquid V tp pass around the plunger proper 54 and enter the space underneath the same. Accordingly, upon the release ofthe turning movement the springV T operates to bring the carriage S downward to its normal position and the 'first part of the re-- proper 54 having elongated valve stems 67 i extending upwardly and appreciably above the upper end of the cylindrical extension 58"* of the plunger member 54 and guided axially by holes 70 in a pair of s iders 68 and 69 sccuredto the exterior of tie extension 58a. The lower spider 68 is secured to the lower body portion of the said extension 58* by means of a central hole 71 that fits over the same and the upper spider 69 has a central hole 72 that fits over a neck 73 extending upward from the upper end of the said extension 58a and is secured to the said neck. Collars 74 are fixed on the stems 67 and coil springs 75I are loosely mounted thereon and the upper ends bear against said collars and th .lower ends against the lower'spider GS and operate tofhold the valves SG normally in the closed position, and the collars 74 separated an appreciable distance from the upper spider 69.

Lifting the carriage S1 operates initially to lift the liquid V and the pressure of the liquid operates to open the valves 65, whereby the movement of the carriage S1 in the initial opening direction is essentially unrestrieted. In the return movement eti'ected by the spring T the rst part thereof is also unrestricted unt-il the position is reached in which the valve 65 is closed` vdien further return movement is restricted in the man- 40 ner describedfor` the style of hinge shown in Fig. 1.

My spring check hinge as described comprises spring means for returning the parts to the normal positions, means for checking 45 the return movement, and separate means for adgustlngthe returning and checkingI means.
